SPOTLIGHT.

. Application filed June 26, 1924. Serial No. 722,435.

To all whom it may concern:

Be it known that I, CLARENCE P. DAVEY, a citizen of the United States, and a resident of Marion, in the county of Grant and State of Indiana, have invented certain new and useful Improvements in Spotlights, of which the following is a full, clear, and exact description.

The invention relates to spot-lights of the ty e adapted to be manipulated on the outslde of the vehicle from the inside thereof. Its object is to provide an improved spotlight of this type which can be easily installed, is simple in construction and can be easily operated to project a column of light in substantially all directions.

The invention consists in the several novel features hereinafter set forth and more particularly defined by claims at the conclusion hereof. I

In the drawings: Fig. 1 is a side elevation of a spot-light embodying the invention, showing it secured in the lower rail of a Wind-shield frame, parts being shown in section. Fig. 2 is a vertical longitudinal section, the lamp being broken away. Fig. 3 is a front elevation, the incandescent lamp and reflector being omitted from its supporting bracket. Fig. 4 is a detail'of one of the clampin plates used in securing the device to the wind-shield frame. Fig. 5 is a detail perspective of the bearing sleeve which extends through the frame. Fig. 6 is a section on line 6-6 of Fg. 2. Fig. 7 is a section on line 7 -7 of Fig. 1.

The invention is exemplified in a lamp comprising a reflector 9 provided with a marginal flange 10 in which a lens 11 is suit? ably held. A split ring extends around the flange 10 and the margin of the lensto hold the latter in connected relation to the reflector. The central portion of the reflector 9 is provided with a rearwardly extending flange 13 which is ressed into interlocked relation with a cy indrical sleeve 14. A lamp-socket 14 is secured in said sleeve, and the base of an incandescent lamp 15 is removably held in operative position in the socket by a pin-and-slot connection 15. Sleeve 14 is held in the tubular portion 17 of a lamp-supporting bracket 17 by means of a set-screw threaded to the bracket. The rearend of the tubular portion of bracket 17 is closed, as at 17". Bracket 17 is preferably formed of a strip'of sheet metal bent to form the tubular portion 17 and members extended downwardly to form an arm 18. A sleeve 36 extends through a hole bored in the lower rail 37 of a wind-shield frame. The front portion of said sleeve is disposed outside of the vehicle and is there provided with an enlarged portion 45 terminating at its front end in a shoulder 46. A collar 50 extends and is rotatable around the enlarged portion 45 of sleeve 36 and is preferably formed of sheet metal bent to form a tubular portion 50 and lugs 50*, which are spaced apart and constitute a forwardly extending arm 51. The lamp-supporting bracket 17 is pivotally supported by a pivot 52 supported in said arm 51. Clamping plates 38 and 39 are elongated laterally and have their ends shaped to conformto the front and rear faces of the windshield rail 37 and provide additional bearing surfaces for the sleeve 36. Plate 39 is provided with lugs 40 fitting in recesses 41 in the enlarged portion 45 of sleeve 36 to lock the sleeve against rotation in the wind-shield frame. The sleeve 36 is held against longitudinal movement by a nut 43 which is screw-threaded to a thread on the rear portion of said sleeve. A look washer 42 is interposed between said nut and clamping plate 38. Collar 50 fits between clamping plate 39 and shoulder 46 on sleeve 36. A bolt 50 extends through lugs 50 to clamp the cylindrical portion 50 with greater or less force of collar 50 around the sleeve to frictionally hold the collar against rotation with the force desired and to correspondingly hold the lamp-supporting bracket 17 against such accidental rotation.

A hollow shaft 20 extends longitudinally through sleeve 36 and is slidable therein. The front end of said shaft is provided with a fork 21 to which arm 18 is pivotally connected by a pin 22 which passes through holes in the fork and a curved slot 19 in the lower end of said arm, so that the lamp-carrying bracket, which is pivotally supported at 52, may be rocked in the plane of arm 18 or, radially with respect to shaft 20 by the longitudinal movement of said shaft. The inner end of sleeve 36 is split longitudinally at 36 and screw-threaded, and a nut 44, with a tapered female screw-thread fitting the thread 36', is adapted to adjustably compress the split end of sleeve 36- to frictionally hold the shaft 20 against longitudinal movement cin the sleeve. By adjusting nut 44, the frictional grip of shaft 20 may be varied to suit the individual users and to assure the holding of the shaft against movementresulting from the vibration of the vehiclc. tation of collar 50 may be varied by the adjustment of nut 43 for the same urpose.

The inner end of the shaft20 is provided with a handle 2.3, whereby it may be shifted longitudinally or rotated. The inside of this handle is provided with a chamber 26, in which is disposed a switch which is adapted to be manually operated from the inslde of the vehicle. This switch comprises a pair of separate spring terminals 28, 29 mounted on an insulating block 27. Contact 29 is connected to the lamp-socket 14 in the sleeve 14 by a flexible conductor 32 which passes through hollow shaft 20 and through the back of the bracket 17 The other contact 28 is connected to a conductor 33 which is suitably connected to a battery, as well understood in the art. A slidable contact button 31 is mounted in a cap 30 which closes the rear end of handle 23. This handle is removably secured .to shaft 20, so that the shaft 20 and sleeve 36 maybe passed through the wind-shield before the handle is attached.

The handle is connected to said shaft by means of a stud 24 and a clamping collar 24. The front end of the handle is split, as at 3, so it can be pressed firmly around said shaft. so its inner end will be held in a hole 20 in the hollow shaft. This collar is adapted to be clamped around the handle by a bolt 24. lVhen the collar is removed, the stud can be inserted through the handle and into hole 20" after the shaft 20 and sleeve 36 have been passed through the wind-shield frame.

The lamp and its supporting bracket 17 can be adjusted radially of shaft 20 by shifting the handle 23 forwardly or backwardly by means of the pivotal and sliding connection 22, 19, the bracket swinging around the pivot 52. The bracket 17 and lamp are bodily and rotatably adjustable by the rotation of handle 23, this movement being effected through shaft 20 which will-rotate the bracket 17 and collar 50 together when the handle is rotated, the collar 50 being rotatable around the sleeve 36. By means of these two adjustments, the lamp may be universally adjusted to project a column of light to anydesired point or in any desired direction within the range for which it is designed.

\Vhen the lamp is to be installed, it is only necessary to drill a hole in the wind-shield rail 37 for the sleeve 36. With the handle 23 removed from shaft 20 and clamping-plate 38, washer 42 and nuts 43, 44 removed from sleeve 36, the latter may be inserted into the wind-shield from the front thereof, while The frictional retardance to the ro- Said collar also holds the stud 24' the collar 50, bracket 17 and shaft 20 remain in connected relation. Next, the clam ing plate 38, washer 42 and nuts 43,44 wil be placed in operative osition, whereupon the sleeve will be proper y mounted in the frame. After the sleeve 36 and shaft 20 therein have pended claims, without departing from the 80 spirit and scope of the invention.

Having thus described the invention, what I claim as new and desire to secure by Letters Patent, is:
